Dyes: Industrial scale up

This is a worksheet which looks at various factors which effect the scaling up of laboratory processes to industrial scale in the commercial manufacture of dyes.  Students look at

  • costs of the raw materials for each dye 
  • the percentage yield 
  • size of reaction vessels  
  • energy...

Enzyme technology

In this activity, students are asked to make a bioreactor containing an immobilised enzyme and use it to produce lactose reduced milk. They then assess the effect that temperature has on the enzyme driven reaction within the bioreactor.
